PLOW.

Application filed October l, 1915.

To all whom t may concern:

Be it known that I, FRED `W. A. Tnet-minis, resident of La Crosse, in the county of La Crosse and `State of llVisconsin, have invented certain new and useful Improvements in Flows, of which the following is a full. clear, and exact description.

The invention relates to plows and has for its purpose to provide simple and efficient l0 means whereby the plow share may be firmly secured to the frog and moldboard of the plow, or readily and quickly detached therefrom.

rlhe invention consists in the several novel features hereinafter set forth and more particularly dened by claims at the conclusion hereof.

Figure lis an inverted plan of the plow showing the parts connected together. Figure 2- is an underneath perspective View of the plow with the plow tilted considerably on the cutting edge of the share. Figure 3- is an underneath perspective view of the plow, the plow being tilted somewhat upon its point and showing an angular relation of a lug and threaded rod. Figure 4 is a rear view of the plow tilted upon the wing corner of the cutting edge of the share and showing a di'erent angular relation of the lug and the rod. Figure 5- is a detail on the line af-afof Figure 2. Figure 6 is a view of the clamping lug showing the vertical face adjacent to the landside share and the vertical portion of the frog. Figure 7- is a top view of the clamping lug. Figure 8- is a side view of the locking lever and support for the connecting rod between the lug and the lever. Figure 9- is a view of the face of the lever adjacent to the moldboard and share.

The plow consists of a beam l, rear landside plate 2, and moldboard 6, all being firmly attached to the frog 5. rlhe share 4 consists of the vertical landside portion 3 and the wing portion 4fL which is secured to the frog and the moldboard by means hereinafter described. The frog conforms to and ts against the back face of the moldboard and is secured thereto in the usual manner. The frog 5 is made with angularA portions, one portion being vertical `,and curving rearwardly and upwardly and to which the rear landside plate 2 is attached..

Serial No, 53,533.

and a wing portion 5x curved to follow the curvature of the share and moldboard, thus affording a support for the moldboard and landside on its upper face and to both portions of which the beam is secured by ordinary means not shown herein.

In Fig. 5 the end of the landside vof the frog is indicated by 5a, its free corner by 517 the end of the wing of the frog by 5c and its free corner by 5b.

Attached to the landside 3 of the share is a lug 7, which may be fastened to the landside in a suitable manner through the hole 7 and having an offset portion 7f, the offset portion being thinner than the thickness of the frog 5 as is shown in Figures l, 2, 3 and 4, the arm of the lug extending inwardly from its angle with the offset so as to pass the corner 5d of the vertical portion of the frog angularly, so that while the share is being seated on the frog and against the lower edge of the moldboard the face 7a of the lug will have a wedging action against the vertical corner 5d of the frog and aid in bringing the share into proper seating position on the plow.

The upper face of the lug has the downward offset 7e, see Figures 2, 3, and 6, the offset being shorter than the thickness of the frog as is shown in Figures 2 and 3, and from the lower end of the odset the upper face of the lug extends upwardly and rearwardly with the face 7g lying beneath and adjacent to the lower corner 5b of the forward end of the wing portion of the frog as is shown in Figures 2, 3 and 5, and being at an angle with the under surface of the frog. in Figure 5 the line 5E is intended to show the contour of the under face of the frog, and from which the angle of the face of the lug 7g with the frog is clearly shown.

From this relation of the face 7g to the forward end of the wing portion of the frog it is manifest that as the share is drawn to position7 the face Ig will contact the corner of the frog 5" with a wedging eect, resulting in seating the wing of the share firmly upon the upper face of the frog whenthe rear edge of the share is seated against the lower edge of the moldboard and against the forward edge of the landside plate 2.

By this means there is provided a double wedging, surface on the lug for drawing the landside of the share against the outer Vertical wall of the frog wingwardly7 and the wing of the share downwardly upon the face ot the frog, as the share is being;` pulled rearwardl;7 to its final position adjacent to the inoldboard.

ln Figure 5 the landside 3 and wing); Ll are shown in cross section, the forward end of the lug also is shown in cross section on the linea-o Fig. 2 and the wedgingl effect in both directions is clearlgT man' Cest.

From the examination ot Figures l? Si. l and 5, it is manifest that the inner 'lace o't the landside, the under tace o1'l `the share2 the landside tace 7 of the lui;` and the upper iace T ot the lug form a socket into which the nose or forward end of the frog protrudes as the share is drawn to place, the socket being open on its under and wing; sides, and when the share. is finally seated,

hrerenting lateral and vertical increment ed `.the share with relation to the 'frog'.

Yttearwardly of the angular faces T and 7*' the lug is bent at a sharperanggle to the Vertical wall of the frog., seen more clearly in Figures l and 5. i

Fastened to the wing; portion of the mold- 1ooard is a lever pivoted at l0 near the lower wing portion of the inoldhoard, hy ineans oit the pinl0 extending through the holt hole lOl and properly secured to the mold-- hoard, and extending rearwardly and upwardly; and its upper end `haring a fork 9b with. the jaws 9@ formingv the open slot 9, lsee Fig ires 8 and l0. it the rear face oit the jaws is a round counter sunk portion 9d, see Figures 8 and 9, to receive a washer QI. shown in dotted lines in Figure 8. The rear wall of the slot QfL is shown sloped to allow oiF4 a. considerable angle of the. rod with the support 95 see Figure l. Between the fjaws and through the washer passes the rear `end of the threaded rod Sharinfy 'the :fidjustine` mit 8b in the rear of the ork and contacting' the washer. rThe tort-iard end Ort the rod is pirotally attached to the rear of the lug through the holel therein7 the pivotal relation being' a loose one, affording a universal movement. Figure l shows the rod and the lever in position when the share .has heen properly seated over the frog' and against the inoldhoard.

Extending' downwardly beneath the rear portion of the share is the hook portion ,il v n or the lever, formed with a. herelled vface lo',

and adapted to wedgingly engage therigid hutten 12 on the under or rear face of the The rear' wall oifrtheV hool'li forms a stop for the lever or support, 9. To release the share from the plow all thatis necessary is to loosen the.- nut suiliciently to litt the washer from the recess, when the rod can he slipped out oi" The lever is then give-n a. rear the slot 9a.

he a conjoint action oit the lever, the r fl and the lug' to seat the share again lw'.' in 1 position. Frequently the shares are warped somewhat and the bevelled edge 13 r to bring the rear of the share down to level with the nioidboard.

The operation oi" attaching,` and det .i the share is Very simple and very qu pertorined. u

By examining figures l and il, it will he seen that the rod and lug are atan angle wingwardly with the landside and 1Vvertical portion or the frog; and also that troni the rertical corner 5d oit the frog to the point oiY support of the. rear of the rod 8 in the forli 9b as a straight line indicated hy the diagrammatical dotted line A; the lug and rodai'e transrersel7 at an angle to each other.

By examining Figs. 2 and 3, which gire something' of aside View of the plow troni d inoldhoard side,` it will he found that 't in the corner 5b oit the forward wing porro ion of the frog to the point oi support oi i 8 in the support 9, as a straight-line 1n- Iod 'lic td by the dotted diagrannnatical line i lug and the rod are at an angle to each tl er in a vertical direction.

.lt is inani'test that as the nut 8b is i' ened against the forl 9") and because or two angular relations ot the ahore described, the rear oit he 'forced Sider-.ave ti "ard the ot thc frog a... iinst the corner 4 .rardly toward. the under lace o and aggainst the comerr 5l* there clamping' etlect.
